Here are the three formulas of motion for an object moving in a straight line under constant acceleration:
Displacement (s):
s = ut + (1/2)at^2
where s is the displacement, u is the initial velocity, a is the constant acceleration, and t is the time elapsed.
Final Velocity (v):
v = u + at
where v is the final velocity, u is the initial velocity, a is the constant acceleration, and t is the time elapsed.
Final Velocity (v) in Terms of Initial Velocity (u), Acceleration (a), and Displacement (s):
v^2 = u^2 + 2as
where v is the final velocity, u is the initial velocity, a is the constant acceleration, and s is the displacement of the object.
